Characteristics

Remark:

The reference level for the relative attenuation arel of the TFS150T is the minimum of the pass band attenuation amin. The minimum of the pass band

attenuation amin is defined as the insertion loss ae. The reference frequency fc is the arithmetic mean value of the upper and lower frequencies at the 3 dB

frequency response of the filter in the operating temperature range. The bandwidth shift of the filter in the operating temperature range is included in the

production tolerance scheme.
